Although I'm sure there are some folks who would disagree, I decided to order Knit Pick's Palette yarn for my sweater. My in-laws sent me some money for my birthday last month. I initially thought I'd spend it on something other than yarn, but that didn't happen!
I don't have a color card for Palette, but I do have a color card for Jamieson's yarns. Using that, a Jamieson & Smith-to-Jamieson's conversion chart, pictures on Ravelry of other Hillswick Lumbers, and comparing what Palette balls I already have to pictures Knit Picks has online and in their printed catalog, I ordered the colors I thought would best match what the pattern calls for. (I found the photos in the catalog to be the most accurate.) Palette didn't come in the blue-violet I needed, so I ordered 2 skeins of Jamieson's purple (#610). So far the yarns are playing well together!
I've gotten through the ribbing and have finished the first repeat of the first pattern. I'm quite pleased with it so far! The colors are much brighter than the photo in the book, but seem to be in-line with photos I've seen on Ravelry, and with photos Ms. Feitelson shows of parts of this sweater in examples throughout her book.
